when RULE_INIT {
set static::SNAT_0 "10.80.0.100"
set static::SNAT_1 "10.80.0.101"
set static::SNAT_2 "10.80.0.102"
set static::SNAT_3 "10.80.0.103"
}
when CLIENT_ACCEPTED {
find SNAT pool
eval "set snat_id \$static::SNAT_[expr { [clock format [clock seconds] -format %W] %4 }]"
log local0. $snat_id
snat $snat_id
}
This would cycle a list of 4 snat IPs/pools (%4 - modulus 4 in the equation) per week.
